The photos definitely don't match the description of the product. I wish the picture of the label on the aliexpress site was clearer. AFAIK, the 1.1A has the word "1.1A" on the label but the 1.1 doesn't. There is some contention as to whether there is a real difference between 1.1A and 1.1 or if it's nothing more than an OEM vs retail designation (see
here).
As long as you don't get a 1.0 (bad sensor) it should be fine. I'll be curious what you actually end up with

I used my WMO through college and then some until it was orange (yes, I moved past yellow) but I don't think I could get another one. The thumb button is too useful for me. The IntelliMouse though...maybe...hmm...
